In the drawings I have shown my device as mounted on a frame work A with the wheels B set in spaced apart support members C on each sidethereof with the wheels B of the rubber or pneumatic type, preferably. The frame work A is of a U-shape with the wheels mounted in the ends of the U, and with an extension Al on the front end thereof by which the entire device is attached to the power medium. 1 i r The ends of the U are bifurcated to form bear-- ings for the shafts or axles of the wheels and along eachinner side of the U legs I secure spaced apart parallelpairs of angled tracks 1 upon which rollers 2 operate. Each roller 2 is attached to a control arm 3 and the control arm is attached to a cross bar 4,. The centerof the bar 4 is attached to a connecting rod 5 which has the front end extended intoacylinder 7 and-' attached to a piston 8. Thus when the piston is actuated forward and backward in the cylinder, the rollers are moved forward and back over the tracks. This is to raise and lower the scoop or conveyor body D. of the machine, and 'the body D is made with a cross support bar 9 extending across the bottom of the body and-up each side a short distance where it isthen'bent outwardly as a support for the body, and as a pivot pointv or fulcrum on which the body is operated. Onto each end of the support bar 9 I then attach control and support beams 10, which beamsare pivotally supported from ,the front end of eachfside'of the frame A by support brackets or blocks 11 raised above'the level of-the frame. A. The beams lilare curved so that the rear end ofthe beam is Ol'lfi. lower level than the front when the device is in the lowest position, but on approximately the same level when the scoop is raised. The lower edge of the beams 10 are resting upon the top side of the rollers 2 at all times and the rear or front position of the rollers, determines the raised or lowered position of the body. A short flat space 12,is provided in the beams at that position which will hold the device in the half raised position as desired for conveying.

From near each end of the frame A I mount the legs of an inverted V-shaped support 13with the medial portion or apex of the V straightened out to provide a space on which 'the upper end of a hydraulic cylinder E is mounted. The hydraulic cylinder E carries a piston 14 therein and from the top end thereof a connecting rod 15 is extended with the end of the rod 15 attached to a link bar 16. Surrounding the cylinder I then provide a sliding bracket 17, with the top end of the bracket carrying a support roller 18 therein, said roller to engage and ride on a rail 19, which rail is secured directly over the hydraulic cylinder E, but spaced slightly thereabove. The two lower ends of the bracket carry rollers 20 and 21 which rollers engage the under sides of guide rails 22 and 23, which rails are secured under, but spaced from the cylinder E. Thus when the piston is operated up and down the cylinder, this bracket is moved up and down the outside of the cylinder. From this bracket running to the top of each side of the body D I provide actuating arms 24 and 25 pivotally attached to the bracket and to a cross brace 26 of the body D.

' An end gate 27 is provided for the rear end of the body D and the said gate is supported from two spaced apart brackets 28 with the front end of the brackets extended forward and secured pivotally on the cross brace 26 of the body D. Extending upward from the brackets 28 near the braces '26 I provide vertical bars 29 and from said bars leading down to theb'eams near the end gate I provide rods 30, said rods secured onto the top end of the bars 29 and extended therebeyond and having a looped end in said rods into which actuating cables or chains 31 are attached. The other end of the cables are attached to the top end of the supports 13 by members 32 secured thereto. The gate 27 remains closed at all times except when the body is tilted rearwardly at which time the cables 31 tighten and pull on thebars 39 and as the body continues to tilt rearwardly taking the slack out of the cables they actuate the arms 29 and rods and draw the gate 27 upwardly away from .thebottom of the body D, so that the body may be either loaded or dumped from the rear.

i Onto the ends of the tracks 1, I then secure guidemembers 35 which are to guide the beams 10 in their up and down movements on the rear end to keep the body from side motions. These guides 35 are formed U-shaped at the top and are then bent out and down to allow the rollers 2 to operate therebetween and are then bent in to engage the tracks 1 and are secured thereto. The rear ends of the members 35 are closed by plated 36 with slots 37 therein in which slots the beams operate.

- Onto the portion A1 of the frame A, I mount apump 40 having a power connection 41 to and into which the power take off drive shaftv 42 from the tractor or truck is placed to drive the pump from the motor of the hauling and powera lead line 43 to control valves 45 and 46 and a pipe 44 leads into the valves from the opposite side of the pump. The valves are provided with control rods 4'7 and 48 to shift the valve elements therein to control the flow of fluid in the direction desired. The valve 45 is connected with the power cylinder E by lines 49 and 50, the line 49 leading into the top end of the cylinder and the line 50 into the bottom end thereof to drive the piston 14 in either direction in the cylinder desired by shifting the valve and directing the fluid into either. end of the cylinder desired.

Leading from the valve 46 I provide lead lines 51 and 52 to ends of the cylinder '7 to control the movement of the piston 8 therein, thus providing means for power actuating the cylinders from the draft vehicle.

The operation of the device is as follows:

The driver wishing to load from the rear actuates the cylinder E by directing fluid through the pipe 50 and driving the piston 14 up the cylinder, thereby tilting the body back, he then lowers the body to the work by actuating the piston 8, drawing the piston forward in the cylinder by forcing fluid through the line 51. The driving vehicle is then backed until the body is filled and the body is then raised to the horizontal position by forcingfluid through the line 49 until the body is horizontal. It may then be elevated for carrying, by actuatingthe piston 8 until the rollers 2 rest under the portions 12 of the arms 10.

To dump the loaded body the driver actuates the cylinder E in either direction desired to dump from the front or rear as desired.

The loading from in front is accomplished with similar methods.

Having thus described my invention I desire to secure by Letters Patent and claim:
